MouseEvent: screenY property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The screenY read-only property of the MouseEvent interface provides the vertical coordinate (offset) of the mouse pointer in screen coordinates.
Value
A double floating point value in pixels.
Early versions of the spec defined this as an integer referring to the number of pixels.
Examples
This example displays your mouse's coordinates whenever you trigger the mousemove event.
HTML
html
<p>Move your mouse to see its position.</p>
<p id="screen-log"></p>
JavaScript
js
let screenLog = document.querySelector("#screen-log");
document.addEventListener("mousemove", logKey);
function logKey(e) {
screenLog.innerText = `
Screen X/Y: ${e.screenX}, ${e.screenY}
Client X/Y: ${e.clientX}, ${e.clientY}`;
}
